/**
 * Checks if a resource at the specified URL is available by making a HEAD request.
 *
 * @param url - The URL of the resource to check.
 * @returns A promise that resolves to `true` if the resource is available (HTTP status 200-299), or `false` otherwise.
 *
 * @remarks
 * This function uses the Fetch API to perform a HEAD request, which retrieves only the headers and not the full content.
 * If the request fails due to network issues or an invalid URL, the function logs the error and returns `false`.
